It's batch rendered without a cache (huge cache, errors out on creation), and the fluid container is inside a group which rotates. It's affected by an external turbulence field, other than that nothing too fancy. Few expressions on the emitter to control scale and emission, velocity swirl, etc, high detail solver on.
I did some tests a while ago with heat explosions and whatnot, and when the high-detail rendering was on, it had a similar effect. Any ideas why the high-detail solver would cause it to explode (in a bad way... ;) ) ?
